Embodiment 1
[0029] The invention provides a sealing method for grouting at the joint between prefabricated concrete shear walls and floor slabs, such as figure 1 As shown, the plugging method of grouting at the joint of the prefabricated concrete shear wall and the floor slab includes:
[0030] Step 1, the precast concrete shear wall is suspended and installed on the reserved ribs on the floor, there are four strip gaps between the reserved ribs and the contour line on the floor, from Selecting the first strip slit from the four strip slits to determine the length of the first strip slit;
[0031] Step 2, if the length of the first strip-shaped gap is less than a preset threshold, select a plastic tube matching the length of the strip-shaped gap, and insert the plastic tube into the strip-shaped gap;
[0032] Step 3, filling the prepared seat slurry into the gap between the plastic pipe and the shear wall;
[0033] Step 4, when the seat slurry is filled, pull out the plastic tube to com...

The invention discloses a sealing method for grouting at the joint between a prefabricated concrete shear wall and a floor slab, belonging to the field of construction. The invention includes determining the length of the first strip-shaped gap, if the length of the first strip-shaped gap is less than a preset threshold, then select a plastic tube matching the length of the strip-shaped gap and insert it into the strip-shaped gap, and mix the prepared seat slurry Fill it into the gap between the plastic pipe and the shear wall. When the seat slurry is filled, take out the plastic pipe and repeat the above steps for the remaining three strip-shaped gaps. When all the four strip-shaped gaps are completely sealed, the The grouting sealing at the joint between the prefabricated concrete shear wall and the floor slab. By using the above-mentioned construction method for sealing, compared with the method of sealing by template in the prior art, since the embedded plastic pipe is used, and the seat slurry is applied on the periphery of the plastic pipe for sealing, it can prevent the mold from sticking. Insufficiency leads to the occurrence of falling, which can reduce construction costs.
Description
technical field [0001] The invention belongs to the field of construction, and in particular relates to a sealing method for grouting joints between prefabricated concrete shear walls and floor slabs. Background technique [0002] At present, most of the grouting seals at the joints between precast concrete shear walls and floors are sealed by molds or formwork. However, such a fixed construction operation is complicated, and the phenomenon of unreliable fixing is prone to occur, which increases the construction cost. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a method for sealing the grouting at the joint between the precast concrete shear wall and the floor slab, the method for sealing the grouting at the joint between the precast concrete shear wall and the floor slab, comprising: [0004] Step 1, the precast concrete shear wall is suspended and installed on the reserved ribs on the floor, there ar...
